HELP: can’t get koi to install (no link) from kodi website through new firestick

i used a NEW updated youtube video and after going to favorites in ES File Explorer and adding the path to the koi download page when i scroll down it shows icons for for devices under “Choose Your Weapon” but i can not link a link with the provided fire stick tv remote. i get on my Mac and sure enough i can hover over the android link to click install but not through the fire stick hooked up to my tv

any help would be so much appreciated for this newbie

thank you
